OData Query String Generator

Overview

The OData Query String Generator is a library designed to generate query string parameters for OData APIs using objects and LINQ expressions. It was originally developed for use with the Azure Cognitive Search engine, which leverages the Elastic Search engine.

Features

• Generate OData query strings dynamically using LINQ expressions.
• Supports complex queries, including nested collections and logical operators.
• Handles various data types, including DateTime, Guid, and nullable types.
• Designed to work seamlessly with Azure Cognitive Search and other OData-compliant APIs.

Getting Started

Prerequisites

• .NET Standard 2.0 or higher.
• .NET Framework 4.8 for testing.

Installation

Clone the repository and include the ODataGenerator project in your solution.

git clone <repository-url>

Usage

1. Add a reference to the ODataGenerator project in your solution.
2. Use the FilterGenerator<T> class to generate OData query strings.

Example

using ODataGenerator;
using System;

var filterGenerator = new FilterGenerator<Record>();
var query = filterGenerator.Generate(record => record.Status == Status.Active && record.Number > 100);
Console.WriteLine(query); // Outputs: "Status eq 0 and Number gt 100"

Testing

The project includes a comprehensive test suite in the ODataGeneratorTests project. To run the tests:

1. Open the solution in Visual Studio.
2. Build the solution.
3. Run the tests using the Test Explorer.
